What potential issues can arise when sorting arrays in PHP and using them in conditional statements?

When sorting arrays in PHP, the keys of the array may be reassigned, causing unexpected behavior in conditional statements that rely on specific key-value pairs. To avoid this issue, you can use the `asort()` function instead of `sort()` to sort the array while maintaining the key-value associations. 

// Example of sorting an array using asort() to maintain key-value associations
$data = array("b" => 2, "a" => 1, "c" => 3);
asort($data);

// Conditional statement using the sorted array
if ($data["a"] == 1) {
    echo "Value of 'a' is 1";
}
